TURNSTILE.

Application filed January 23, 1912.

To all whom it may concern Be it known that I, CLEM M. BROOKER, citizenof the United States, residing at Lakewood, in the county of Cuyahogaand State of Ohio, have invented certain new and useful Improvements inTurnstiles, of which the following is a specification.

This invention relates to turnstiles, and particularly to turnstilesintended for use on pay-as-you-enter cars.

The turnstile is one of that type in which the arms drop to verticalposition during part of the revolution, the purpose being to occupy aminimum of floor space. The turnstile is used to control the entry ofpassengers and to register fares, acting thereby as a check on theconductor. Means are provided for locking the turnstile so that theentry of passengers can be delayed when desired, as when the conductoris making change or giving a transfer.

Novel means are provided for raising the arms as the turnstile isrotated, so as to bring them into active position and to hold them sowhile passing the entry.

In the accompanying drawings Figure 1 is a plan view showing theturnstile located in a car. Fig. 2 is an end view of the turn-- stile.Fig. 3 is a side elevation of the same. Fig. 4 is an enlarged detail inplan of the devices for operating the arms. Fig. 5 is a similar view ofa modified device for the same purpose. Fig. 6 is a section at a a onFig. 5. Fig. 7 is a section at BB on Fig. 4. Fig. 8 is a detail insection showing parts of the locking devices and registering mechanism.Fig. 9 is a section at 0 con Fig. 8. Fig. 10 is a bottom view of acasting shown in Fig. 8. Fig. 11' is a detail showing one of the armsstriking a bumper roller. Fig. 12 is a detail in section of the outerend of one of the arms.

The arms of the turnstile are indicated at A, B, C and D. A and B arerubber tired bumper rollers against which the arms come in contact toprevent sudden jarring, the former being struck by the arms when theydrop and the latter by the arms when they are lifted.

3 is a casing which covers part of the mechanism to guard the same.Ateach end the arms have fiber rollers 4 held by a cap 36 and screw 37to a block 35 fastened in the end of the tubular arm by a pin 34. Eacharm is provided at its inner end with a pivot casting 38, which turns ona pivot pin 29 Specification of Letters Patent.

supported by arms projecting from a sleeve carrier casting 21 whichturns on the upper reduced end of a post or shaft 24 which is fixed tothe floor or platform by a foot piece 25.

The arms drop by gravity as they swing beyond the entry way, and theirimpact is checked by the bumper wheel A carried by a bracket fastened tothe back of the casing, and as the dropped arms turn their lower endsare guided and retained by a curved guide 5, attached to the casing,until they reach the position for lifting, and when they are lifted theystrike the bumper wheel B which is supported by suitable brackets 41fastened to the casing.

The lifting devices for raising the arms in succession comprise a blockor casting 7 which is fixed to a rod 48 which works at one end through aguide mounted at the top of the post 24, and at the other end through aguide at 61 at the outer end of a frame 43 which is supported by saidpost and projects horizontally to one side of the post. This castingalso supports rollers 44 which serve as guides for the rod 48.

A spring 6 is coiled around the rod between the end of the frame 43 andthe cast ing 7 so that when the rod is advanced the spring iscompressed. The casting 7 is guided in its movement by a guide G,forming part of the frame 43, which fits in a notch H in the casting 7,and said casting projects outwardly so that it extends into the line ofmovement of the roller 4 at the upper end of each of the arms, when saidarms are in vertical position. Assuming that the turnstile is beingrotated, the roller 4 at the upper end of the rear vertical arm will, asshown in Fig. 4, come in contact with the projection of the casting 7,and will force the same, and the rod 48, in a radial direction,compressing the spring 6, until the roller at the lower end of the armruns off of the track 5. The casting 7 also carries a roller 49 on theunderside thereof, which, when the rod 48 is advanced and the spring iscompressed, is carried beyond the head 38 of the arm. WVhen the arm runsoif of the track 5 the pressure of the spring 6 is released, and saidspring then forces the casting 7 backwardly or toward the center ofrotation, and the roller 49, which is carried by the pin 50, strikes theflat surface K of the casting 38, above its pivot 29, and the force ofthe spring causes the roller to rock the arm and swing the outer endthereof upwardly thereby lifting the arm to the horizontal positionshown at B in Fig. 1, and, the rotation of the turnstile beingcontinued, the roller 4 at the inner end thereof is caught under theguide projection L as clearly shown in Fig. 4, thereby holding the armin raised position. until the roller passes off the end of the guide L,when the arm drops to original or vertical position for the nextoperation.

In the modification shown in Figs. 5 and 6 a frame 42 is used, insteadof the frame 43, said frame being located on the opposite side of thecenter to that shown in Fig. 4, and the rod 48 works in this frame 42,with a spring 6 confined in said frame against a collar 45 secured tothe rod 48 by a pin 46, said collar 45 having a finger 62 which projeetsinto a slot J in the frame to prevent the rod from turning. In thismodification, the head or casting 7 is attached to the inner end of therod 48, in position to receive the impact of the roller 4 on eachdropped arm, as above described, and as the turnstile is operated therod 48 is siifted to the left in Fig. 5, thereby compressing the spring.The subsequent operation; is the same as that above described.

The rotary sleeve 21 turns on ball bearings 32, and is enlarged at thebottom, the enlargement being provided with ratchet teeth F and alsowith projecting pins 30. The ratchet teeth F are adapted to be engagedby the upper end of a rod 23 which works through a guide in a casting 20fastened to the post 24. Said rod 23 is lifted by a lever 13 which isfulcrumed on a bracket 14 under the car platform and is operated bytreadle rod 12 which works through a hole in the car floor where theconductor stands. By pressing down on the treadle the conductor maycatch the rod 23 in one of the notches of the ratchet and so stop therotation of the turnstile. The enlargement on the sleeve 21 is alsoshaped to form cams E which engage a roller 27 at the upper end of a rod22 which is connected through a lever 16, fulcrumed on a bracket 15under the car platform, to a rod 18 which will be connected in anysuitable manner to a fare register (not shown). The rod 18 works througha pipe 17 in the car. A private or check register is also provided andis indicated at 19, with its star wheel or other operating device inposition to be struck by the pins 30 which project from the rotarycasting 21. The arrangement is such that both registers are operated ateach quarter revolution of the turnstile.

Guards 8 and 9 protect the turnstile devices, the latter supporting anetting 11, so that the passengers cannot get in the way of the fallingor rising arms.

What I claim as new is:

1. In a turnstile, the combination of a supporting post, a carrierrotatable thereon, arms pivoted to the carrier, so as to rise and drop,a guide frame mounted on the post, a spring pressed block slidable onsaid frame and having a part projecting into the path of the upper endof the arms when they are dropped to vertical position, whereby thespring is compressed by pressure of the arm against the block as thearms revolve, and a guide engaged by the lower part of the arms andacting to hold the arms down dur ing part of a revolution, said springacting to swing the arms up to horizontal position when they pass off ofthe guide.

2. Ina turnstile, the combination of a supporting post, a carrierrotatable thereon, arms pivoted to the carrier and adapted to rise anddrop during different portions of each revolution, a spring supported onthe post, means actuated by the rotary movement of an arm when invertical position to compress said spring, and a guide engaged by saidarm to hold the latter down while the spring is being compressed, saidspring acting to swing the arm upwardly when it passes beyond the guide.

3. In a turnstile, the combination of a supporting post a carrierrotatable thereon, vertically swinging arms pivoted to the carrier, afixed frame at the top of the post, a spring pressed block slidable onsaid frame and arranged to engage each arm above its pivot during partof a revolution, whereby the block is pressed outwardly and the springis compressed, and a guide engaged by the lower part of each arm whilethe spring is being compressed, said spring acting to press the blockagainst the upper end of each arm to swing the same to horizontalposition when it passes beyond said guide.

4. In a turnstile, the combination of a central supporting post, acarrier rotatable thereon, arms pivoted to the carrier to swing up anddown, a guide frame extending radially from the post, above the carrier,a spring pressed block slidable radially in the guide frame and locatedin the path of the upper ends of the arms when they are in verticalposition, whereby the spring is compressed by pressure of the said upperend against the block as the arms are revolved, a guide engaged by thearms below the pivot thereof and acting to prevent lift of the armswhile the spring is being compressed, said spring and block acting bypressure against the upper ends of the arms to swing the latter tohorizontal position after they pass the guide.

5. In a turnstile, the combination of a supporting post, a carrierrotatable thereon, vertically swinging arms pivoted to the carrier, aguide frame mounted on the post, a rod slidable radially in said guideframe, a

block carried by the rod and projecting into the path of the upper endsof the arms when they are in vertical posit-ion, a spring pressingagainst the block, and adapted to be compressed by the pressure of thearms against the same during part of a revolution, and a guide confiningthearms to vertical position while the spring is being compressed, saidspring and block acting by pressure against the upper end of each arm toswing the latter to horizontal position after it passes the guide.

6. In a turnstile, the combination of a supporting post, a carrierrotatable thereon,

arms pivoted to the carrier to swing up and down, a frame mounted on topof the post above the carrier, said frame having a projection underwhich the inner ends of the arms pass, to hold the arms in horizontalposition during part of the revolution, a spring pressed block slidableradially on the frame and projecting into position to be struck by theupper ends of the arms when they are in vertical position, whereby thespring is compressed by pressure of the arms against said block, and aretainin guide engaged by the lower ends of the arms while the spring isbeing compressed, said block and spring acting by pressure against theupper ends of the arms to swing the latter to horizontal position whenthey pass beyondthe end of the retaining guide, and the block beinglocated adjacent to said projection, whereby the inner ends of the armswill pass from the block under said projection.

7 The combination in a turnstile of a series of arms pivoted to rise anddrop, and bumper wheels supported adjacent to the turnstile in positionto receive the impact of said arms as they are lifted and dropped.

In testimony whereof, I do affix my signature in presence of twowitnesses.
